Unformatted text preview: al component values. Find the % error between the ideal and measured values. There are a variety of methods for determining the time constant from a graph of time response. These include: • • response is of the form . Choose two points where v and t are known, and solve for A and τ. The points can be chosen to minimize error, typically at 90% and 10% of total response. For example, if the initial voltage was 10V and the final voltage was 0, points with voltages near 9V and 1V would be used. Note that A can be eliminated by dividing the equations for the two points Drawing a tangent to the response at t = 0. This intersects the final steady state value at the time constant τ. While fine for ideal circuits, the rapid change at t = 0 can produce a lot of error in the calculation for actual circuits. Solving the equation of the response using two points from the response curve. Suppose the Procedure 2: RC Circuit (30 points) 2.a (5 points) Set
